As usual, Roy has totally missed the point. Roy is talking software system
components, whereas the OP was about programming "black box" modules
within such components.

But getting away from Roy's mistake and concentrating on the actual
matter a hand : Allowing too much access is a VERY bad thing :
programmers do naughty things and leverage optimizations that they
should not know about. When that optimization is then corrupted by the
owner, the reliant systems break. This is a bad thing.

Here's a hint lads : its why "private" exists in C++.

You publish what they need and nothing more. When you publish these
needs correctly then the benefits are manyfold since the programmer
utilising this documented API is (generally) secured against future changes.
